World leaders have concluded a three-day summit on global food security without reaching an agreement on a $44 billion aid package to help the world's poorest farmers.

At a press conference following the summit on Wednesday, FAO Director General Jacques Diouf expressed concern over global food security, saying the hungry cannot wait any longer.

He called for the joint efforts of the international community to tackle the critical situation, adding that he was disappointed with the lack of real progress at the summit.

"To my regret, the official Declaration adopted by the Summit this past Monday contains neither measurable targets nor specific deadlines, which would have made it easier to monitor implementation," he said.

The organization says the global food output should increase by 70 percent in order to feed a projected population of 9.1 billion in 2050.

Every six seconds one child dies of malnutrition in the world and more than one billion people now face hunger and malnutrition, more than at any other time in history.

None of the leaders of the Group of Eight leading industrialized nations attended the summit with the exception of Italian Prime Minister Silvio Berlusconi.

"This issue could have been tackled here and it's a missed opportunity," Nathalie Enroll from Doctors without Borders told Press TV's Correspondent in Rome. "People are not going to be fed with words."
